Added code to support that force index can be used to force an index scan instead of a full table scan. Currently this code is disable but I added a test to verify that things works if the code is ever enabled. Other things: - FORCE INDEX will now work with "Range checked for each record" and join cache (see main/type_time_6065) - Removed code ifdef with BAD_OPTIMIZATION (New cost calculations should fix this). - Removed TABLE_LIST->force_index and comment that it should be removed - Added TABLE->force_index_join and use in the corresponding places. This means that FORCE INDEX FOR ORDER BY will not affect keys used in joins anymore. Remove TODO that the above should be added. I still kept TABLE->force_index as it's used in test_if_cheaper_ordering() and opt_range.cc - Removed setting table->force_index when calling test_quick_select() as it's not needed (force_index is an argument to test_quick_select()) |

MariaDB: The open source relational database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:

Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss, MariaDB's Zulip instance, https://mariadb.zulipchat.com/
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.
New contributors can ask questions any time, but we will provide immediate feedback during that interval.
